SPECIFICATION forming part of Letters Patent No. 546,863, dated September 24, 1895.

Application filed April 26, 1895. Serial No. 547,210. (No model.)

To all whom it may concern.-

Be it known that I, EMIL NOPPEL, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Lift and Force Pumps, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a novel construction of a lift and force pump and its adjuncts which is especially applicable for cleaning clogged outlet-pipes of sinks, tanks, drains, and similar devices; and it consists of a rotary barrel and a valve with ports, whereby when the barrel is rotated the ports will be opened and closed.

` It further consists of novel details of construction, all as will be hereinafter set forth.

Figures l and 2 represent longitudinal sectional views of a pump and its adjuncts embodying my invention, showing the different relative positions of the suction and discharge ports and a portion of a sink or tank to which the same is applicable. Fig. 3 represents an end View of the discharge-outlet when the parts are in the position, seen in Fig. l. Fig. 4 represents a section on line fr 0c, Fig. 2.

Similar letters of reference indicate corresponding parts in the several gures.

Referring to the drawings, A designates the cylinder or barrel of a pump, in which reciprocates the piston B, having the stem C, which is preferably square, as in the present instance, and passes through the cap D, which is attached to the extremity of said barrel and is provided with ports or vents E.

F designates the base or foot of said barrel, said base having therein the ports G and H, which are used for suction and discharge, respectively, it being noted that said ports are not diametrically in line with each other, as will be understood from Figs. 3 and 4.

J designates a screw-cap or coupling-ring, which is adapted to be secured in any suitable manner to the outlet end of the pump, adjacent the base F, said cap having a flange K thereon, which extends inwardly and serves to hold in place the flange L of the Valve M, which is placed in contact with the outer face of said base F, said valve M having therein the inletport N and the tubular port P, which also serves as an outlet, as will be explained, said port P having the nipple or nozzle Q attach ed thereto, which is engaged by the pipe R, the latter being provided with a bushing S, which may be of rubber or other suitable material and may have a shoulder, if desired, said bushing S being adapted to be inserted inthe drain-pipe T of the tank or sink U, as willbe hereinafter explained.

V designates a plate which is attached to said flange K and is provided with shoulders W X, which serve as stops and limit the rotary movement of the barrel A and the valve M relative to each other, owing to the contact of the wall of the port P or N with said shoulders, as will be explained, the position of said plate relative to the ports G and H being understood from Figs. 3 and 4.

Y designates a suitable handle which is attached to the pipe R.

The operation is as follows: When the outlet-pipe T of the sink, tank, or other receptaole becomes clogged up, the pipe R is inserted in said outlet and held lirmly therein by means of the handle Y. The barrelAis then rotated a short distance by means of the rod or stein C until the parts assume the position seen in Figs. l and 3, the ports G and N being in alignment and the port H out ofcommunication with the port P, and if now the piston B is drawn outwardly, as indicated by the arrow, Fig. l, the water will enter the barrel. If now the barrel A is rotated, preferably to the right, as in the present instance, as indicated by the arrows in Figs. 3 and 4, until the port N is out of alignment with the port G, the port I'I will then be in alignment with the channel or port P and the parts will now be in the position seen in Figs. 2 and 4. It now the piston B is moved in, as indicated by the arrow, Fig. 2, it will be seen that the contents of the barrel A will be forcibly discharged from the pipe R into the drain T, and will thus tend to dislodge any impediment or obstruction which may exist in the latter. Should it be desired to pump water or iiuid from the drain-pipe and discharge it into the tank or sink U, the barrel is rotated so that the parts are in position as in Fig. 2. Then the piston is drawn out and the fluid enters the barrel. Now rotate the barrel so that the parts are in position as in Fig. 1. The piston is now moved in, whereby the fluid is IOO forced from the barrel through the ports G and N into the tank or sink, and so discharged into the latter.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In alift and force pump having a rotary barrel, a base with ports out of alignment with each other, and a valve freely located on said base having ports adapted to register alternately with the ports of said base, one of the ports of the valve having a branch for connection with the place of service of the pump, substantially as described.

2. In a lift and force pump having the barrel A, the base F in its lower extremity, the ports G and H, the valve M adjacent said base, having the flange L, and the ports P and N therein, the pipe R and the bushing S, said parts being combined substantially as described.

3. In a lift and force pump, a barrel with a coupling ring secured to its discharge end, a valve with ports between said coupling ring and barrel, and a plate secured to said coupling ring and having shoulders adapted to be engaged by the walls of said ports, said parts being combined substantially as described.

4. In a lift and force pump, a barrel, a cap secured on its head having an angular open- 3o ing therein, a piston with a stem in said opening, a coupling ring on the discharge end of the barrel, and a valve between said ring and the end of the barrel, said parts being combined substantially as described.

5. In a lift and force pump, a barrel, apiston therein, the base of said barrel having a plurality of ports therein, a movable valve held against said base, having a plurality of ports adapted to register with the ports of said base, a pipe attached to one of said ports provided with a bushing, a handle attached to said pipe, means for holding said valve in position, and means for limiting the movement of said valve and barrel relative to each other, substantially as described.

6. A lift or force pump, consisting of a barrel with a cap on its head with openings therein and a plurality of ports in its base, a piston with a stem angular in cross section passing through said cap, a coupling ring secured to its base and a valve having ports therein between said coupling ring and base, said parts being combined substantially as described.
